You are correct, I have an old antec cleaning kit.. (bought few years ago)
But it is no more available on amazon or flipkart. Surprisingly search results still show those on top though not available LOL
Fluffy works better. Picks up dust well. You only need water and no other products. If required mix some mild dish liquid detergent
I have several of them, general dusting, hand & dish drying, phone & laptop clean
Once done it goes into the washer with several others with a liquid detergent
Non targeted products are cheaper, this thing is for polishing cars not sold for screens but still works.
My laptop touchpad gets so filthy, couple of swipes and it looks like new. Works great with phone screens. If the cloth is not fluffy it takes more wipes and is less effective
